Detailed description of the invention
Embodiment: the present embodiment power lithium ion battery pole piece automatic checkout equipment is as shown in Figure 1, including station dial 1, feed mechanism 2, vision-based detection mechanism (not shown) and cutting agency 3, being provided with four fixing magazines 4 on the circumferencial direction of station dial equally spacedly, two groups of cameras of feed mechanism 2, cutting agency 3 and vision-based detection mechanism and light source distinguish in corresponding four fixing magazines 4.
Feed mechanism 2 and cutting agency 3 except raw material magazine, certified products magazine, defective products magazine structure different except, the structure of remainder is identical, therefore following only the structure of blanking part is elaborated.
Cutting agency 3 includes certified products magazine 5, defective products magazine the 6, second cantilever the 7, the 3rd sucker the 8, the 4th sucker the 9, second runing rest 10, second drives axle 11 and the second camshaft 12, wherein the middle part of the second cantilever 7 is fixing with the top of the second runing rest 10 is connected, 3rd sucker 8 and the 4th sucker 9 are installed on the two ends of the second cantilever 7 symmetrically, 3rd sucker 8 is installed on the reciprocating mechanism centered by the 4th sucker towards fixing magazine, certified products magazine 5 and defective products magazine 6；Second driving axle 11 is provided with the second partial gear 13 and the 3rd gear 14, second partial gear 13 engages with the be installed on the second runing rest 11 second complete gear 15,3rd gear 14 engages with the 4th gear 16 being installed on the second camshaft 12, and the bottom of the second runing rest 10 is against the second camshaft 12.
Vision-based detection mechanism is made up of industrial camera, strip source and data handling machine etc..When detecting pole piece defect, adopt annular light source, it is possible to make the picture quality that industrial camera obtains higher.Owing to pole piece defect kind is various, improving detection quality while guaranteed efficiency, so same pole piece is performed twice at detection, that respectively detects pole piece wants half region.
As in figure 2 it is shown, be provided with Timing Belt between Geneva mechanism 1-1, feed mechanism 2 and cutting agency 3.Geneva mechanism is that active pin wheel is when active rotation, driven sheave is stirred to realize equal angular intermittent movement by straight pin, active pin wheel is made constant speed clockwise and is rotated continuously, and when straight pin is introduced into radial slot, sheave is static by the Locking arc pinning of actively pin wheel evagination because the Locking arc of indent；When straight pin enters the radial slot of driven sheave, two arcs disengage, driven sheave being rotated by straight pin；When straight pin departs from radial slot again, another circular arc of driven sheave is lockable again, it is achieved thereby that the unidirectional intermittent movement of sheave.Motor 1-2 simultaneously drives Geneva mechanism 1-1, feed mechanism 2 and cutting agency 3 by Timing Belt, and its internal incomplete gear mechanism and cam mechanism engage also by gear and be synchronized with the movement, it is achieved that four-axle linked.
As shown in Figure 3, cam is when 0 °, sucker has drawn, from the fixing magazine station dial, the pole piece detected, cam is from 65 °, partial gear starts to engage with complete gear, runing rest turns over 180 °, namely the sucker not drawing pole piece forwards the position of the fixing magazine of station dial to, the sucker having drawn the pole piece detected forwards to above the magazine of blanking, when 250 °, sucker begins at and moves down under the effect of cam, during to 325 °, sucker arrives fixing magazine and draws pole piece, the magazine of blanking put into the pole piece drawn by the sucker of cantilever opposite side simultaneously, complete blanking action.The explanation of above-mentioned cam curve movement is for the curve movement of cutting agency, and the cam curve movement of feed mechanism is identical with cutting agency.
With the above-mentioned desirable embodiment according to the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not necessarily departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, it is necessary to determine its technical scope according to right.
